For the first time, a panel of US health experts backed a drug to prevent HIV infection in healthy people.

The panel has recommended US regulators to approve the daily pill, Truvada, for use by people considered at high risk of contracting Human Immunodeficiency Virus. Currently the drug is already approved by the US Food and Drug Administration (FDA) for people who are HIV-positive, taken along with other anti-retroviral drugs.

Even though the FDA is not required to follow the panel's advice, but it usually does.

Some health workers and groups active in the HIV community have opposed the approval of the drug for fear of abuse of the drug and abandonment of safer sex practices. This can potentially result in drug-resistant strains.

Some, however, say the move could prove to be a new milestone in the fight against HIV/Aids.
